    The Conundrum of Sharing Research Data
    Christine L. Borgman
    2013, (5): 1-20.  DOI: 10.11925/infotech.1003-3513.2013.05.01

    Researchers are producing an unprecedented deluge of data by using new methods and instrumentation. Others may wish to mine these data for new discoveries and innovations. However, research data are not readily available as sharing is common in only a few fields such as astronomy and genomics.Data sharing practices in other fields vary widely. Moreover,research data take many forms, are handled in many ways, using many approaches, and often are difficult to interpret once removed from their initial context. Data sharing is thus a conundrum. Four rationales for sharing data are examined, drawing examples from the sciences, social sciences, and humanities: (1) to reproduce or to verify research, (2) to make results of publicly funded research available to the public, (3) to enable others to ask new questions of extant data, and (4) to advance the state of research and innovation. These rationales differ by the arguments for sharing, by beneficiaries, and by the motivations and incentives of the many stakeholders involved. The challenges are to understand which data might be shared, by whom, with whom, under what conditions, why, and to what effects. Answers will inform data policy and practice.

    A Feature Selection Based on Consideration of Multiple Factors
    Lu Yonghe, Li Yanfeng
    2013, (5): 34-39.  DOI: 10.11925/infotech.1003-3513.2013.05.04
    In the process of feature selection, term’s weight determines whether the term can be a feature. But the weight is affected by many factors, the main factors are term’s importance, characteristics and representative. With the consideration of those factors, a new function TW (Term Weight) based on the importance of the feature and the ability of category distinguishing, is brought to be an improved method to select features. After that, experiments on the comparison between term’s CHI, IG and TW validate that TW can increase the weight of special features in a class and can decrease the weight of unimportant features. Finally, the validity of the new algorithm in feature selection is proved by the classification experiments on Chinese classification corpus by three classifiers.

    Recommended Method for Cross-language Term Synonymous Relationship and Its Empirical Research
    Song Peiyan, Li Jingjing, Zhao Xing
    2013, (5): 40-45.  DOI: 10.11925/infotech.1003-3513.2013.05.05
    Synonym of terminology is a basic type of relationships between terms. Based on the English-Chinese alignment dictionary, this paper proposes recommended method of term synonyms, deriving of Chinese and English translation in pairs, and optimizes synonyms results by weighted optimization measure. The experiments indicate that both the accuracy and efficiency of synonym recognition are improved by the method, which is beneficial to the construction of knowledge organization systems, encyclopedias and information retrieval.

    Research of Books Recommendation of Borrow Preference Uncertainty in University Readers Based on Cloud Model and Multi-feature
    Li Kechao, Lan Dongmei, Ling Xiaoe
    2013, (5): 54-58.  DOI: 10.11925/infotech.1003-3513.2013.05.07
    The paper, taking advantages of cloud model in expressing uncertainty of fuzziness and randomness in nature, proposes that there are uncertainties in cloud model and readers’ multi-featured books preference.The paper computes the weighted similarity of readers’ majors, genders and grades,uses the backward cloud algorithm to compute readers’ preference of borrow-return time interval that is expressed in cloud expectation, entropy and hyper entropy,and then computes the readers’ cloud similarity. Combining multi-featured similarity of readers with cloud similarity,the paper finally recommends books to readers with copied ones and proves the validity of the algorithm by experiments.

    Wang Lin, Zhao Yang, Shi Kan
    2013, (5): 73-79.  DOI: 10.11925/infotech.1003-3513.2013.05.10
    Based on the network collective behavior on micro-blog public opinion, laws and perception of implementation intentions have become a hotspot for early warning and public opinion research. Therefore, the purpose of this study through three online micro-blog experiments is to explore the laws of collective behavior on micro-blog public opinion from the topic heat and trend, emotional heat, social semantic networks and micro-blog influence. The results indicate that firstly implementation intentions of the micro-blog collective behavior are affected by the topic heat and trend, emotional heat, network centrality, the number of fans, number of attention and original; secondly implementation intention of value-orient, safe-orient and control-orient exhibited significant are differences in topic trend, emotion changes, micro-blog influence, social semantic networks etc. Therefore, the results of the experimental study have certain implications to make guide strategy for micro-blog hot events, and it may provide practical guidelines for strengthening social management and crisis response.
